论文摘要
具有三维跟踪的第一个定向暗物质搜索，具有头尾灵敏度（3D矢量跟踪分析），使用气态的三维TARCKING检测器或Newage-0.3B'检测器进行。该搜索是从2013年7月到2017年8月（运行14至Run18）在Kamioka地下实验室进行的。总的生计是434.85天，对应于4.51千克$ \ cdot $天的暴露。获得$ 4.3 \ times10^{2} $ pb的自旋依赖性wimp-proton横截面的90％置信度上限，质量为150 GEV/$ C^2 $。
The first directional dark matter search with three-dimensional tracking with head-tail sensitivity (3d-vector tracking analysis) was performed with a gaseous three-dimensional tarcking detector, or the NEWAGE-0.3b' detector. The search was carried out from July 2013 to August 2017 (Run14 to Run18) at the Kamioka underground laboratory. The total livetime is 434.85 days corresponding to an exposure of 4.51 kg$\cdot$days. A 90 % confidence level upper limit on spin-dependent WIMP-proton cross section of $4.3 \times10^{2}$ pb for WIMPs with the mass of 150 GeV/$c^2$ is obtained.
